public domain

The present disclosure relates, for example, to wireless communication systems, and more particularly to antenna structures for wireless communication.

Related technical description

Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and others. These systems may be multiple-access systems capable of supporting communication with multiple users by sharing available system resources (eg, time, frequency, and power). Examples of such multiple-access systems include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, and Orthogonal Frequency Division Multiple Access (OFDMA) systems.

As an example, a wireless multiple-access communication system may include several base stations, each base station simultaneously supporting communication for multiple communication devices (or referred to as user equipment (UE)). A base station may communicate with UEs on downlink channels (eg, for transmission from the base station to the UE) and uplink channels (eg, for transmission from the UE to the base station).

Communication systems may employ licensed spectrum, unlicensed spectrum, or both. Unlicensed millimeter-wavelength mmW spectrum in the high gigahertz (GHz) band is emerging as a promising technology, for example for multi-gigabit wireless communications. Spectrum around 60 GHz has several advantages over other lower frequency systems, including increased unlicensed bandwidth, compact size of transceivers due to smaller wavelengths (about 5 mm), and increased atmospheric absorption due to higher atmospheric absorption. minor interference. However, there are several challenges associated with this spectrum, such as reflection and scattering loss, high penetration loss and high path loss, which limit the coverage at 60 GHz. To overcome this problem, directional transmission can be employed. Thus, a technique known as beamforming using a multi-element antenna array can be used for mmW wireless communication.

However, even with beamforming, communications using mmW spectrum can benefit from antenna structures designed especially for such wavelengths. Conventional antenna structures designed for lower frequencies (eg, 800MHz, 900MHz, 1800MHz, 1900MHz, 2100MHz, etc.) may include a single omnidirectional antenna (sometimes two or three for diversity) and may not be suitable for mmW spectrum applications.

In particular, the antenna structure can be designed to be integrated with the external housing of the wireless communication device.

Detailed Description

When a mmW antenna is included in a wireless communication device, the mmW antenna may be configured to receive and/or transmit communication signals through an external housing of the wireless communication device. The external housing may conventionally form the rear cover of the device, with the display screen being arranged on the front side of the device. Due to the electromagnetic shielding of the display, the reception/transmission of communication signals can be restricted to pass through the back cover. Furthermore, electromagnetic shielding may prohibit the placement of back covers made of metallic materials on mmW antennas.

A plastic material may be used for the back cover at least on the mmW antenna to allow reception/transmission of communication signals through the mmW antenna. However, the radiation of such communication signals may still be distorted by reflections and/or refractions caused by the back cover on the mmW antenna.

Accordingly, the antenna structure can be designed to be integrated with the external housing of the wireless communication device. The outer housing may include a cavity that enables the antenna element of the antenna structure to receive and/or transmit radio frequency communication signals. As such, metallic or non-metallic (eg, plastic) materials may be used for the outer housing. An antenna element of the antenna structure may be aligned with the cavity to receive and/or transmit communication signals via the cavity.

The following description provides examples and does not limit the scope, applicability or examples set forth in the claims. Changes may be made in the function and arrangement of elements discussed without departing from the scope of the disclosure. Various examples may omit, substitute, or add various procedures or components as appropriate. For example, the methods described may be performed in an order different from that described, and various steps may be added, omitted, or combined. Likewise, features described with reference to some examples may be combined in other examples.

1 illustrates an example of a wireless communication system 100 in accordance with various aspects of the present disclosure. The wireless communication system 100 includes a base station 105 , a UE 115 and a core network 130 . Core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Base station 105 interfaces with core network 130 via backhaul link 132 (eg, S1, etc.) and may perform radio configuration and scheduling for communication with UE 115, or may operate under the control of a base station controller (not shown). In various examples, base stations 105 can communicate with each other directly or indirectly (eg, through core network 130 ) over backhaul link 134 (eg, X1 , etc.), which can be a wired or wireless communication link.

Base station 105 may communicate wirelessly with UE 115 via one or more base station antennas. Each of these base station 105 sites may provide communication coverage for a respective respective geographic coverage area 110 . In some examples, base station 105 may be referred to as a base transceiver station, radio base station, access point, radio transceiver, Node B, evolved Node B (eNB), Home Node B, home eNode B, or other some suitable term. The geographic coverage area 110 of the base station 105 may be divided into sectors (not shown) that constitute only a portion of the coverage area. The wireless communication system 100 may include different types of base stations 105 (eg, macro and/or small cell base stations). There may be overlapping geographic coverage areas 110 of different technologies.

In some examples, wireless communication system 100 is an LTE/LTE-A network. In LTE/LTE-A networks, the term evolved Node B (eNB) may be used generally to describe base station 105 and the term UE may be generally used to describe UE 115 . The wireless communication system 100 may be a heterogeneous LTE/LTE-A network where different types of eNBs provide coverage for various geographic regions. For example, each eNB or base station 105 may provide communication coverage for macro cells, small cells, and/or other types of cells. Depending on the context, the term "cell" is a 3GPP term that can be used to describe a base station, a carrier or component carrier associated with a base station, or a coverage area (eg, sector, etc.) of a carrier or base station.

A macro cell typically covers a relatively large geographic area (eg, several kilometers in radius) and may allow unfettered access by UEs with a service subscription with a network provider. In contrast to a macro cell, a small cell is a low power base station that can operate in the same or a different (eg, licensed, unlicensed, etc.) frequency band than the macro cell. According to various examples, small cells may include pico cells, femto cells, and micro cells. A picocell may cover a relatively small geographic area and may allow unfettered access by UEs with a service subscription with a network provider. A femtocell may also cover a relatively small geographic area (e.g., a home) and may provide for restricted access by UEs associated with the femtocell (e.g., UEs in a Closed Subscriber Group (CSG), the home) access of the UE in the user, etc.). An eNB for a macro cell may be referred to as a macro eNB. An eNB for a small cell may be referred to as a small cell eNB, a pico eNB, a femto eNB, or a home eNB. An eNB may support one or more (eg, two, three, four, etc.) cells (eg, component carriers).

Wireless communication system 100 may support synchronous or asynchronous operation. For synchronous operation, base stations may have similar frame timing, and transmissions from different base stations may be approximately aligned in time. For asynchronous operation, base stations may have different frame timings, and transmissions from different base stations may not be aligned in time. The techniques described herein can be used for synchronous or asynchronous operations.

A communication network accommodating some of the various disclosed examples may be a packet-based network operating according to a layered protocol stack. On the user plane, communications at the bearer or Packet Data Convergence Protocol (PDCP) layer may be IP-based. A radio link control (RLC) layer can perform packet segmentation and reassembly for communication on logical channels. A Medium Access Control (MAC) layer may perform prioritization and multiplexing of logical channels into transport channels. The MAC layer can also use hybrid ARQ (HARQ) to provide retransmission of the MAC layer, thereby improving link efficiency. On the control plane, a radio resource control (RRC) protocol layer may provide establishment, configuration and maintenance of RRC connections between UE 115 and base station 105 or core network 130 supporting radio bearers for user plane data. At the physical (PHY) layer, transport channels may be mapped to physical channels.

UEs 115 are dispersed throughout wireless communication system 100, and each UE 115 may be stationary or mobile. UE 115 may also include or be referred to by those skilled in the art as a mobile station, subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal , mobile terminal, wireless terminal, remote terminal, handset, user agent, mobile client, client, or some other suitable term. UE 115 may be a cellular telephone, a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a tablet computer, a laptop computer, a cordless telephone, a wireless local loop (WLL) station, or the like. A UE may be capable of communicating with various types of base stations and network equipment, including macro eNBs, small cell eNBs, relay base stations, etc.

Communication link 125 shown in wireless communication system 100 may include uplink (UL) transmissions from UE 115 to base station 105 and/or downlink (DL) transmissions from base station 105 to UE 115 . Downlink transmissions can also be referred to as forward link transmissions, and uplink transmissions can also be referred to as reverse link transmissions. Each communication link 125 may include one or more carriers, where each carrier may be a signal (eg, a waveform signal of a different frequency) composed of multiple subcarriers modulated according to the various radio techniques described above. Each modulated signal may be sent on a different subcarrier and may carry control information (eg, reference signal, control channel, etc.), overhead information, user data, etc. Communication link 125 may communicate bidirectional communications using FDD (eg, using paired spectral resources) or TDD operation (eg, using unpaired spectral resources). A frame structure of FDD (for example, frame structure type 1) and a frame structure of TDD (for example, frame structure type 2) can be defined.

In some embodiments of system 100, base station 105 and/or UE 115 may include multiple antennas for employing an antenna diversity scheme to improve communication quality and reliability between base station 105 and UE 115. Additionally or alternatively, base station 105 and/or UE 115 can employ multiple-input multiple-output (MIMO) techniques that can exploit a multipath environment to transmit multiple spatial layers carrying the same or different encoded data.

The wireless communication system 100 may support operation over multiple cells or carriers, a feature that may be referred to as carrier aggregation (CA) or multi-carrier operation. A carrier may also be called a component carrier (CC), layer, channel, and so on. The terms "carrier," "component carrier," "cell," and "channel" are used interchangeably herein. UE 115 may be configured with multiple downlink CCs and one or more uplink CCs for carrier aggregation. Carrier aggregation can be used with both FDD and TDD component carriers.

One or more of base stations 105 may be mmW base stations. In some cases, wireless communication system 100 may be a mmW communication system configured to communicate with UE 115 via mmW radio frequency communication signals. In other cases, the wireless communication system 100 may be heterogeneous, such as involving LTE/LTE-A base stations that may communicate with UE 115 using LTE/LTE-A frequencies and mmW base stations that may communicate with UE 115 via mmW frequencies network of.

As noted above, wireless communications using the mmW spectrum can benefit from antenna structures designed specifically for that spectrum. Accordingly, the mmW base stations 105 of the wireless communication system 100 and the UEs 115 configured for mmW communication may have specific antenna designs. For clarity, antenna designs for mmW communications are described below with respect to wireless communications devices, such as cellular telephones. However, such antenna designs may also be applicable to mmW base stations as appropriate or desired.

Turning now to FIG. 2 , shown is a cross-sectional view of an example of an antenna design 200 for a wireless communication device in accordance with various aspects of the present disclosure. Antenna design 200 may include an outer housing 205 . One or more cavities 210 may be formed in outer housing 205 . In the cross-sectional view of Fig. 2, two cavities 210 are shown as an example. The thickness of outer housing 205/depth of cavity 210 may be a design parameter that may be customized for a given application.

The antenna design 200 may also include an antenna structure 215 including one or more antenna elements 220 and a substrate 225 supporting the antenna element(s) 220 . While the antenna element 220 is shown disposed on top of the substrate 225, it should be understood that the antenna element 220 may be coplanar or recessed from the substrate 225 as appropriate or desired. For example, substrate 225 may be a printed circuit board (PCB). Substrate 225 may be disposed adjacent to (eg, along) an inner surface of outer housing 205 . Thus, the substrate 225 can be placed such that there is no gap between the substrate 225 and the outer housing 205, which can prevent signal loss due to reflection.

In the cross-sectional view of Fig. 2, two antenna elements 220 are shown as an example. Antenna elements 220 may be aligned with corresponding cavities 210 in outer housing 205 such that antenna elements 220 may receive and/or transmit communication signals via corresponding cavities 210 . Thus, depending on the particular antenna design, the number and arrangement of cavities 210 may correspond to the number and arrangement of antenna elements 220 . For example, the cross-sectional view of FIG. 2 may represent an antenna design including a 2X1, 2X2, 2X3, 2X4, 2X5, or 2X6 array of antenna elements 220 with a corresponding array of cavities 210 in outer housing 205 .

Antenna structure 215 may also include a radio frequency integrated circuit (RFIC) 230 that may be electrically connected to antenna element 220 via substrate 225 . RFIC 230 may provide operational control for antenna element 220 (eg, for receiving/transmitting communication signals via antenna element 220 ).

For purposes of understanding, antenna design 200 is illustrated as including a main control board 235 (eg, another PCB) that provides operational control of the wireless communication device, including but not limited to communication controls. The main control board 235 may be electrically connected to the RFIC 230 and the antenna element 220 via the substrate 225 to facilitate mmW communication of the wireless communication device.

As shown, each of cavities 210 may include walls 240 that are tapered to slope toward the respective antenna element 220 . The taper of walls 240 may facilitate collection of communication signals to and/or radiation of communication signals from corresponding antenna elements 220 for reception and/or transmission, respectively. The taper of the wall 240 may be a fixed slope or may be variable (eg, curvilinear) as appropriate or desired. Where the cavities 210 have curved cross-sectional perimeters (eg, circular or elliptical when viewed from above in FIG. 2 ), each cavity 210 may have a single wall 240 . Where the cavities 210 have rectangular cross-sectional perimeters (eg, rectangular or square when viewed from above in FIG. 2 ), each cavity 210 may have two pairs of opposing walls 240 .

The outer housing 205 may be made of plastic material (or other non-metallic material such as glass). In such cases, the wall 240 of the cavity 210 may have a layer of metallic material 245 (eg, gold plating) disposed thereon, as represented on the right side of the cavity in FIG. 2 . The metallic material 245 may collect/radiate communication signals of the corresponding antenna elements 220 by reflecting such signals.

Alternatively, the outer housing 205 may be made of a metallic material. In such cases, the walls 240 of the cavity 210 may collect/radiate the communication signals of the corresponding antenna elements 220 by reflecting such signals without additional layers of material, as represented on the left side of the cavity in FIG. 2 .

The outer housing 205 may be provided with a coating 250 (such as a protective layer) on its outer surface. As shown, coating 250 may extend over cavity 210 . Coating 250 may be a relatively thin layer of colored material that conceals the visual appearance of cavity 210 for aesthetic purposes without adversely affecting reception/transmission of mmW communication signals therethrough.

Alternatively or additionally, cavity 210 may be filled with a suitable dielectric or non-metallic material 255 to provide a surface coplanar with the outer surface of outer housing 205 . Where coating 250 is included, material 255 may provide support for coating 250 on cavity 210 as opposed to having cavity 210 evacuated or filled with air or other gas (which would not provide suitable support for the coating). For mmW communication signals, material 255 may be transmissive (eg, transparent) so as not to adversely affect reception/transmission of mmW communication signals therethrough. For example, a plastic material such as a resin (eg, (modified )) or polycarbonate (for example, ).

3 illustrates a cross-sectional view of another example of an antenna design 300 in accordance with various aspects of the present disclosure. Antenna design 300 may include an outer housing 305 . One or more cavities 310 may be formed in outer housing 305 . In the cross-sectional view of Fig. 3, three cavities 310 are shown as an example.

Antenna design 300 may also include antenna structure 315 including one or more antenna elements 320 and a substrate 325 supporting antenna element(s) 320 . In the cross-sectional view of Fig. 3, three antenna elements 320 are shown as an example. Antenna elements 320 may be aligned with corresponding cavities 310 in outer housing 305 such that antenna elements 320 may receive and/or transmit communication signals via corresponding cavities 310 . Thus, depending on the particular antenna design, the number and arrangement of cavities 310 may correspond to the number and arrangement of antenna elements 320 . For example, the cross-sectional view of FIG. 3 may represent an antenna design including a 3X1, 3X2, 3X3, 3X4, 3X5, or 3X6 array of antenna elements 320 and an array of corresponding cavities 310 in outer housing 305 .

Antenna structure 315 may also include RFIC 330 that may be electrically connected to antenna element 320 via substrate 325 . For purposes of understanding, antenna design 300 is illustrated as including main control board 335 that may be electrically connected to RFIC 330 and antenna element 320 via substrate 325 to facilitate mmW communication of the wireless communication device.

As shown, the right and left cavities 310 may each include walls 340 that are tapered to slope toward the respective antenna elements 320 . The right and left cavities 310 may each include opposing less tapered (eg, not tapered as shown) walls 345 . Similarly, the intermediate lumen 310 may have one or more walls that are less tapered (eg, not tapered as shown). This arrangement may allow the antenna design 300 to be more compact compared to the antenna design according to FIG. 2 having the same number of antenna elements and cavities each with tapered wall(s). For example, where the cavities 310 have a rectangular cross-sectional perimeter, the outer wall 340 of each of the cavities 310 may be tapered, while the inner wall 345 (e.g., one of the cavities facing oppositely to the wall of the adjacent another cavity) Each wall of ) may be less tapered or not tapered.

The outer housing 305 may be provided with a coating 350 (such as a protective layer) on its outer surface. Alternatively or additionally, cavity 310 may be filled with a suitable dielectric or non-metallic material 355 to provide a surface coplanar with the outer surface of outer housing 305 .

4 illustrates a cross-sectional view of yet another example of an antenna design 400 in accordance with various aspects of the present disclosure. As shown, the antenna design 400 may include an outer housing 405 having a cavity 410 formed therein, an antenna structure 415 including an antenna element 420 and a substrate 425 supporting the antenna element 420, an RFIC 430, a main control board 435, and a coating 450, Each of these may be as described above with respect to FIGS. 2 and/or 3 .

As shown, antenna design 400 may also include auxiliary cavities 440 for corresponding cavities 410 . Each of the auxiliary cavities 440 may be formed in the substrate 425 and aligned with the corresponding cavity 410 and the corresponding antenna element 420 . The auxiliary cavity 440 may be filled with a suitable dielectric material such that the antenna element 420 is placed between the corresponding cavity 410 and the dielectric material of the auxiliary cavity 440 .

A first metal layer 445 may be disposed on top of the substrate 425 , where the cutout area corresponds to the antenna element 420 . A second metal layer 460 may be disposed on the bottom of the substrate 425 . The auxiliary cavity 440 may be surrounded by a metal plated through hole 455 which may extend between the first metal layer 445 and the second metal layer 460 . Alternatively, the walls of the auxiliary cavity 440 may have a layer of metallic material (eg, gold plating, not shown) disposed thereon. The first metal layer 445 and/or the second metal layer 460 and the metal plated through hole 455 may collect/radiate communication signals of the corresponding antenna elements 420 by reflecting such signals. Although not illustrated in FIG. 4 for clarity, the feed lines (not shown) for each antenna element 420 may also be surrounded by additional metal plated through-holes (not shown).

5 shows an exploded perspective view of yet another example of an antenna design 500 in accordance with various aspects of the present disclosure. As shown, the antenna design 500 may include an outer housing 505 having a cavity 510 formed therein, and an antenna structure 515 including an antenna element 520 and a substrate 525 supporting the antenna element 520, each of which may be as described above with respect to FIGS. 2 and/or 3. as described. As illustrated, lumen 510 may have a pyramidal shape with four tapered walls, although other shapes (eg, different cross-sectional perimeters, non-pyramidal, asymmetrical, etc.) may also be employed. Additionally, cavity 510 may be filled with a suitable dielectric material 550, such as described herein. Although not shown for clarity, antenna design 500 may include an auxiliary cavity for cavity 510 , such as described with respect to FIG. 4 .

FIG. 6 shows an exploded perspective view of an example of an antenna array 600 according to various aspects of the present disclosure. As shown, the antenna array may include an outer housing 605 with a plurality of cavities 610 formed therein, and an antenna structure 615 including an antenna element 620 and a substrate 625 supporting the antenna elements 620, each of which may be as described above with respect to FIG. 2 and/or 3 as described. Additionally, cavity 610 may be filled with a suitable dielectric material 650, such as described herein. Although not shown for clarity, antenna array 600 may include an auxiliary cavity for each of plurality of cavities 610, such as described with respect to FIG. 4 . Although the illustrated antenna array 600 is a 2X4 array, it should be understood that arrays of different numbers of antenna elements 620 and cavities 610 are also possible.

7 illustrates an example of an external housing 705 for a wireless communication device in accordance with various aspects of the present disclosure. As described herein, external housing 705 may be part of an antenna design for mmW communications. Thus, while specifically shown in FIG. 7 and not described for simplicity, it should be understood that the outer housing 705 may be employed with various other features described herein to achieve a particular antenna design.

External housing 705 may form the back cover of a wireless communication device, such as a cellular telephone. Although the outer housing 705 is shown as having a particular shape, the shape shown is intended to be illustrative and not limiting.

The outer housing 705 may include a first portion 705-a and a second portion 705-b. The first portion 705-a may have a plurality of cavities 710 formed therein. As such, the first portion 705-a may generally correspond to the portions of the outer housing 205/305/405/505/605 illustrated in FIGS. 2-6.

The first part 705 - a can be inserted into the second part 705 - b to form the outer housing 705 . For example, the first part 705-a may be assembled with other components of a particular antenna design (eg, antenna element(s), antenna substrate, RFIC, etc.) and then inserted into the second part 705-b. The first and second portions 705-a and 705-b may be fitted together in any suitable manner (eg, friction fit, mechanically connected, glued, etc.).
